Research paper thumbnail of A Selection Design of Experiment for Optimization of Process Variables for Supercritical Carbon Dioxide Using Response Surface Methodology: A Review

Lecture Notes in Mechanical Engineering, 2021

Supercritical carbon dioxide (SC-CO2) which is an alternative and green method for extraction of ... more Supercritical carbon dioxide (SC-CO2) which is an alternative and green method for extraction of natural plants. Many parameters in SC-CO2 including pressure, temperature, extraction time, particle size, CO2 flowrate and composition of solvent modifiers were optimized to improve the extraction efficiencies by using a response surface methodology (RSM). RSM is a collection of statistical and mathematical techniques useful for developing, improving, and optimizing processes. To adequately resolve the above-mentioned issues, a design of experiment (DOE) is required. Recently, in providing a better decision support analysis, the necessity for a specific experimental design modelling is based on statistical methodologies via response surface. Hence, objective of this study is to review the previous studies on various innovative designs that have been employed for SC-CO2 extraction using RSM Consequently, the present paper provides an insight into RSM by scrutinizing the design, modelling, predicting, and optimizing SC-CO2 process with an acceptable accuracy for different designs of experimental work with an appropriate model that fits the desired approach of the researchers.

Research paper thumbnail of Supercritical Carbon Dioxide Extraction of Hevea Brasiliensis Seeds: Influence of Particle Size on to Oil Seed Recovery and its Kinetic

Malaysian Journal of Fundamental and Applied Sciences, 2021

Pressure 30 MPa, temperature 60 oC and average particle size 500 µm gives the maximum oil recovery (34.71%), diffusivity coefficient (5.13 E-12 m2/s) and extraction rate (0.6 mg/sec). The morphological characterization of extracted rubber seeds was done on the basis of scanning electron microscopy which was parallel with the results of the effect of particle size. The results obtained from gas chromatography-mass spectrometry showed that the rubber seeds oil contained significant essential fatty acids and certain chemical constituents which are very valuable.

Research paper thumbnail of Mini review: Application of supercritical carbon dioxide in extraction of propolis extract

Propolis cannot be utilized as raw material, due to its complex mixture of compounds. Hence it must be separated by the extraction process. Extraction targets to removes the inert compounds in the propolis sample and preserves the flavonoids and polyphenolic fraction. The most common technique used in propolis extraction is solvent extraction that involves the use of solvents such as ethanol, water, hexane, ethyl-acetate and chloroform. However, this conventional technique has some drawbacks including strong residual flavour, possible adverse reactions, harmful to the environment, low quality of the extract and long process period requi...
